RE: ETL for Flexcab Sample Requests failed with file size error

[Techow, Ric]

Thanks Steven,

What is happening is that files on Zos are being zipped and shipped to a 
Solaris platform as a data feed.  Zos PKZIP has an option to generate a gzip 
format compressed file.  So we have done that for many years - worked fine till 
recently.

It appears that when Zos PKZIP encounters a file > 4 GB changes format to ZIP64 
- (should have abended instead of doing that without letting folk know).  
Solaris gzip has been failing).  

I'll try the info-ziplink you have suggested.

Thanks for you help.

   Exactly what you're doing is not entirely clear to me, but ...

   Why are you using gzip to handle archives created by PKZIP?  I
thought that PKZIP worked with ZIP archives, and that gzip's ZIP-archive
capabilities were quite limited.

   There are programs which were designed to deal with ZIP archives, and
they have been used on z/OS:

      http://www.info-zip.org/

   I'm not a z/OS user, so I know nothing, but there is at least one in
the Info-ZIP group, so you may be able to get some help if you have
problems building or using the Info-ZIP Zip and UnZip programs on z/OS.

   It's not my program, so I know nothing, but I would not bet that gzip
on any system type can do this.  The Info-ZIP programs definitely _can_
handle large-file ZIP archives on Solaris (although a version number
would be an interesting datum when describing any OS).  HP-UX, Tru64,
and VMS, too, for that matter.
